For legs, I'll squat on the smith machine. I'll put on 3 45lb. Iron pies on each side, and several 10lb. pies as well....I'll do 4 to 6 reps, drop a 10 pounder, 4 to 6 reps, drop another...no rest, and I go to complete failure.....

This is good for bench as well, but ensure you have good people to spot....

You do not need to do this but once, or twice a month at the most....Generally, I will lose my cookies doing this for legs, and yes you will feel very sick to your stomach...the reason being, when you push your legs very hard, it pulls a vast amount of blood from the upper body to meet the demand the legs are screaming for....

Now, to avoid this....once you complete the strip sets, and are able to walk...heh heh heh....go straight to the lat pull, or cable crossover and use a fairly light weight and do slow easy reps to pull some blood back to the upper body....this works sometimes...sometimes it doesn't....I personally love the delicious pain they bring...But, I am right much of a pain freak.....Enjoy...!!!
